Abstract (en)
[origin: EP0710790A1] The device has a unit (9,10), to press the sealing element (6) with a preset force against the valve seat (7), when the armature piston (11) is in initial stroke position. The unit has a coil (9) around the piston, which is supplied with current separately of the exciting coil. When a preset current variation is present, the second coil cancels the force of the sealing element acting on the valve seat. The closing force is applied in initial stroke position by the second coil. To cancel this force, the current supply to this coil is switched off via a switching unit.
